FOND DU LAC, Wis. — A retired prison guard ate his 25,000th Big Mac on Tuesday, 39 years to the day after eating his first ... nine. Don Gorske was honored after reaching the meaty milestone during a ceremony at a McDonald’s in his hometown of Fond du Lac. Surely McDonald’s most loyal customer, Guinness World Records recognized Gorske’s feat three years and 2,000 Big Macs ago, and the 57-year-old says he has no desire to stop. “I plan on eating Big Macs until I die,” he said.
